One of the weird things, among many obviously, among Australians is that you bump into them all over the place. I remember sitting in a park in Austria with my American sheila about 20 years ago, I was wearing a green and red rugby jersey. Someone yelled out in broad Strine: "go the bunnies". Bunnies being a shortened version of "Rabbitohs", the team that wears red and green. That same weekend we were up at Hitler's mountaintop retreat and she said to me "see that guy over there, from the top he is wearing I know that he went to the same university as me, in fact I know his fraternity and I guarantee that we know some of the same people, but I'd never dream of just walking up and talking to him about it. But you bump into some random Australian and you act like you're long lost best friends. You people are so weird".
But the good part is that I got her hooked on us, After she dumped me for being too old and not living in America, she went and married an Australian banker in London and they are still together.
That said, some of the Aussies I've known in far flung places have been among the biggest dicks on the planet.
